API 11AX rod pump

The raw material of API 11AX rod pump parts should be inspected after heat treatment, the mechanical properties, chemical compositions and metallographic structures must be inspected by batch. The API 11AX rod pump parts should be inspected several times during the processing procedure. Some key points like the outer diameter of the plunger and the inner diameter of the pump barrel should be 100% inspected.

  • Advanced production equipment for machining, spraying welding, electroplating, and honing.
  • Sealing performance tests must be carried out 100% after finishing the assembly of the whole rod pump.

The plunger and the pump barrel are assembled into one body, and is inserted into the oil pipe with the sucker rod.

There are fixed barrels and movable barrels.

According to the position of the support assembly, it is divided into two types: the top fixed and the bottom fixed.

According to the support assembly types, it is divided into cup type and mechanical type

Compared with the tubing pump, the rod type pump has the characteristics of not having to take off the oil pipe when the pump is down, and has a large variety of options.

Easiness to operate, saving more than half of the operating time can greatly reduce operating costs, suitable for deep well use.

Rod pumping wells are widely used over the world out of China.

If you are looking for API pump manufacturers, Sanjack is your best choice.

Rod pump

Rod pump

The first letter R standing for Rod (commonly called insert).

Usually Insert pumps are the first choice because they can be serviced simply by pulling the sucker rod string.

Insertable pumps can be removed from the well without having to remove the production tubing.

Compared with the tubing pump, the rod-type oil well pump has the characteristics of no need to set up and down the tubing when lifting the pump, and a wide choice of various forms.

It is easy to check the pump and save more than half of the operating time, which can greatly save operating costs and is suitable for deep well use.

Rod pump can be further optimized by selecting the metallurgy and coating of various components to maximize pump life in specific well conditions.

  • Installed on the end of a sucker rod string as a complete unit.
  • Can be ran deeper than Tubing Pump.
  • Special service applications are available for most types.
  • Less service cost than a tubing pump.
  • Removed from the well without having to remove the production tubing.
  • Advanced production equipment for machining, spraying welding, electroplating, and honing.
  • Sealing performance tests must be carried out 100% after finishing the assembly of the whole rod pump.
